Water is of fundamental importance for human life; access to water of good quality is of vital concern for mankind. Currently however, the situation is under severe pressure due to several stressors that have a clear impact on access to water. In the Arctic, climate change is having an impact on water availability by melting glaciers, decreasing seasonal rates of precipitation, increasing evapo...

Environmental pollution constitutes a great health hazard to human, animals and plants with local, regional and global implications. Pollution has adverse effects on land, water and its biotic and a biotic components. Effluents from industries are normally considered as the main industrial pollutants containing organic and inorganic compounds The increasing agricultural reuse of treated effluen...

Groundwater recharge using reclaimed water is considered a promising method to alleviate groundwater depletion. However, the pollutants in the reclaimed water would be recharged into groundwater during this process and pose risk to groundwater and human. In this study, 12 isomers of NP were detected in the reclaimed water and receiving groundwater in Feng River and Yanggezhuang. The variation r...

introduction: colored compounds which often are toxic and carcinogen is one of the environmental pollutants. these pollutants should be removed prior than discharge to the environment. the aim of this study was the evaluation of maize tassel powder efficiency for the removal of reactive red 198 dye from synthetic textile wastewater. materials & methods: this experimental study was performed in ...

Titania nanoparticles sensitized with metal-free organic dye exhibit high visible-light activities for the redox conversion of water pollutants in a wider pH range in comparison with TiO(2) sensitized with ruthenium bipyridyl complexes.

The use of UV and Vis light (in the form solar energy) in presence semiconductor nanostructured materials as photocatalysts is effective for adequate removal a wide spectrum pollutants (resistant to other degradation techniques) various types wastewater, which are important elements development science related photocatalysis [...]

Utilization of water in different parts of industrial life cycles brings a huge concern on environmental water and wastewater pollutions. In this research, environmental quality assessment of wastewater is studied using fuzzy logic. Fuzzy appliance is due to existance of statistical considerations (including standard deviations), various uncertainties, non-linearity and complexity of functions....

While over seven million organic and inorganic compounds that have been indexed by the American Chemical Society's Chemical Abstracts Service in their CAS Registry are commercially available, most pollution monitoring programs focus only on those chemical stressors for which regulatory benchmarks exist, and have been traditionally considered responsible for the most significant human and enviro...
